Bone marrow transplant, means your blood can have the donor DNA

Did you know that if you have a bone marrow transplant, your blood can have the donor’s DNA and your salival and hairDNA will be your own. It has caused people to be wrongly arrested based on DNA evidence.

Would the DNA profile from someone who has been the recipient of a whole blood transfusion reflect some (any?) characteristics of the blood donor. If so, how long would these characteristics remain? Could the use of DNA evidence be negated by claiming to have donated blood that went to the person the police should be looking for?

This question just goes to show what happens when you watch too much Court TV. More educational than MTV, but, man, you’ve opened a can of worms.
